By the time I got up to speed and started to have any real fun in an E92 M3 I had to start to slow down. Car is great but you need to get the revs up and the V8 comes to life. Lack of low end torque is something I did not fully grasp/know I wanted so badly until I took delivery of my car and realized how much fun you can have with a properly set up turbo car.
1M is fun from 0 all the way up. If its any consolation have someone sit in the passenger seat of a 1M and and M3 and see which car excites/scares them more under acceleration
